SWITCH-STAND.

SPECIFICATION forming part of Letters Patent No. 249,706, dated November 15, 1881.

' Application filed August 18, 1881. (N0 model.) I

To all whom it may concern: v

Be it known that I, FREDRIC O. WEIR, of Cincinnati, Hamilton county, State of Ohio, have invented a new and useful Improvement in the Mechanism of Switch-Stands and Targets for Operating Switches, of which the following is specification.

Figure l is a perspective view of my invention. Fig. 2 is a broken central section of same. Fig. 3 is a detailed view of the wrench-shaped end adjusting-lever. Fig. 4 is abroken rear elevation of Fig 1. Fig. 5 is a detail view of target of same.

The object of my invention is to furnish a device for operating and positivelylocking the crank of a switch-stand as close as possible to the crank itself without. having to lift the crank and shaft, with its connections, and thus prevent the liability of the rails being sprung out of place laterally while the wheels are passing over them; also, to furnish a simple and effective device for locking said locking-lever.

The object of the invention is attained by using a column or frame, A, supportinga vertical shaft, 13, and crank O, and it having the crank-arm extended beyond the crank pin 0 sufficiently to permitof the Wrench orfork shaped end adjusting-lever D dropping astrideit, and at the same time dropping into notches E E provided for it and cast into the column or frameat the different points to which the switch is arranged to be turned, both at the top ofthe stand and at the bottom,as close to the crank as is practicable. By this meausI am enabled to provide against and effectually prevent a possibility of the rails being sprung sidewise.

At the top of the stand I provide a jointed latch, F, one end of which is secured to the vertical shaft B and the other havinga slot, 6,

at the proper distance, so that when the lock- 40 in g-lever is locked over the crank this lockinglatch can be dropped down onto the top ofsaid locking-lever, and a padlock passed through the top of said lever at H, eifectually locking the switch againstits movementby parties not 5 authorized,as well as against the spring of the crank by the passage of trains over it.-

The manufacture of the target 1 maybe simplified byforming from the single piece ofmetal of which the target is made the necessary cor- 5o rugations to permit of one portion, J, of the metal passing around one-halt of the vertical shaft B, and the other portion, J, extending around the other half of said shaft B, thus avoiding a special forgingthat is usually made and riveted to the target for holding it in position.

Havingdescribed my invention, wliatl claim 1. Aswitch-staud having the pivoted adj ustinglever adapted to lock with the bottom crank and simultaneously latching into the base of the switch-stand, substantially as specified.

2. Aswitch-stand having an adjusting-lever arranged to drop into notches provided for it in the bodyofthe switch-stand, and having an adjustable latch, one end of which is secured to the vertical shaft of the switch-stand and the other end engaging with the lever in such a manner as to be secured by a padlock.

In testimony whereof Ihave hereunto set my hand in the presence of two subscribing witnesses.
